F Size Introduction

The following is the introduction to F Size. FEPA-F, There are multiple standard versions for grain sizes. The European FEPA (Federation of European Producers of abrasives). Within the FEPA sizes, you can also distinguish between FEPA-P and FEPA-F. F sand is an applied particle size specification for abrasives and refractories materials. The particle size numbers are: F4, F5, F6, F7, F8, F10, F12, F14, F16, F20, F22, F24, F30, f36, F40, F46, f54, F60, F70, F80, f90, F100, F120, F150, F180, F220, F220, F230, F240, f280, F320, F320, f280, F320, F320, f280, F320, F360, F400, F600, F800, F1000, f1200. Among them, f4-f220 is called “grit size,” which is produced by screening, and f230-f1200 is called “micro powder,” which is produced by multi-purpose water separation, airflow and ultrasonic circular vibrating screen Welcome to contact us to exchange what is F Size meaning? and look forward to your information.

What’s lead time for bulk order?

1)for 5~25 tons, it takes around 10~15days. 2)For 26~200 tons,20-40days We will try to deliver it with the promise of quality guarantee as soon as possible

What is a mesh vs. Grit size?

If you take a (1) inch space and add wires to it, the number of openings within the 1″ space is defined as mesh. For example, if the 1″ space has ten openings for particles to fall through, then that sieve would be called a 10 mesh sieve. Typical sieve

What is melting vs. Sintering?

When processing minerals in a furnace, materials can either be melted or sintered.  When materials are melted during the production process the minerals go from a solid state, to a liquid state, then is re-solidified during the cooling process creating uniformity in the chemistry throughout the entire batch. The sinerting process

What is your terms of payment?

T/T 30% as deposit, and 70% before delivery. We’ll show you the photos of the products and packages .before you pay the balance.

How about your delivery time?

How is fused alumina obtained?

Raw materials containing aluminium oxide are electrothermally melted at a reaction temperature of more than 2,000 °C to produce the various fused aluminas. Different starting materials are used depending on the desired type of fused alumina. For instance,
